The mass accommodation coefficient of gas-phase HCl and HBr on ethylene glycolwater surfaces has been measured as a function of water mole fraction (01) and temperature. The gas uptake studies were performed under liquidvapor equilibrium conditions using a droplet train flow reactor. The mass ...

摘要: a Tetramethyl ammonium chloride was used as electrolyte.b The amount of HCl per mole of protein was the same in all experiments. The pH was measured only on the solution con- taining no glycol.DOI: 10.1016/S0021-9258(18)60301-1 被引量: 68 ...
Hydrogen diffusion across a steel (Cт3) membrane from 0.01–1.0 M HCl in ethylene glycol containing water (0.1 and 5 wt %) was studied. The effect of the solvate form of the discharging proton (C 2 H 4 (OH) 2 H + and H 3 O + ), the concentration of H + solv , and the ...

All chemical compounds were of analytical grade, including tetraethyl orthosilicate (TEOS), cetyltrimethylammonium bromide (CTAB), n-butanol, hydrochloric acid (HCl), ethylene glycol, ethanol, Ni (NO3)2·6H2O, as well as PdCl2, and supplied by Merck. Pluronic P-123 was procured from Sigma Al...
2.3 Triethylene glycol dimethacrylate (TEGDMA) Oxidation of ethylene in presence of silver oxide (AgO2) catalyst at high temperature forms ethylene oxide which after hydration gives TEG as reaction product. Methacrylic acid when reacts with triethylene glycol (TEG) forms a dimethacrylate known as TEGD...
The HCl is removed with an absorbent and substantially pure carbon dioxide is collected. The absorbent-contacted stream can be subjected to catalytic deoxidation in the presence of hydrogen to convert unoxidized oxygen introduced in the catalytic oxidation to water. 展开 ...
Ethylene Glycol 1.Used as an antifreeze agent in the coolant in for example, automobiles and air-conditioning systems. 2. Used as a de-icing fluid for windshields and aircraft, as an antifreeze in automobile engines. 3. Used as an important precursor to ...
